EGG-BEATER.

Specification of Letters Patent.

Patented March 12, 1907.

' Application filed June 15,1906. Serial No. 321,872.

To all whom it may concern.-

Be it known that I, ANDREW J. THOMPSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in E g-Beaters, of which the following is a speci cation.

This invention is an egg-beater, and it is characterized particularly by a construction having two beater-loops, one of which is made to rotate in one direction and the other in the opposite direction. This produces a very efiicient and rapid action. The construction is also such that the beater can be operated with one hand, which is advanta eous, because it leaves the other hand free to old the bowl or vessel containing the eggs or other matter to be beaten or stirred.

In the accompanying drawin s, Figure 1 is a plan View of the device with t e handle up. Fig. 2 is a similar view with the handle pushed down. Fig. 3 is a section on the line 3 3 of Fig.1.

Referring specifically to the drawin s, 6 indicates an outer loop or beater-blade aving an upwardly-projecting extension forming spaced side bars 7, connected across at the top, and said crossiece has an opening or slot through which t e upper part- 8 of a s iral rod extends. The openin is of proper s ape to run on the spiral, so that a rotary motion of the loop is roduced. The bars 7 are braced near the ower ends by a crosspiece 9, through a round hole in which the lower end of the spiral rod works.

At 10 is indicated an inner loop or beaterblade, and this is mounted to rotate upon a pivotin 11, set in the outer loop, at the bottom t ereof. The inner loop has at the top extensions 12, connected by a cross-piece 13, which has an opening through which the lower portion 14 of the spiral rod works, the opening being shaped to run on the spiral, and conse uently to rotate the inner loop.

The rod referred to has right and left spirals, the upper part of the rod, which operates the outer loop, being of one hand and the lower portion of the rod, which operates the inner loop, being of the other hand. The twist changes or reverses at a stop 16, consisting of a crossin which strikes the crosspiece at the to 01 the uprights 7, and so lim- 1ts the upwar movement of the rod. This upward movement is produced by a spring 17, coiled around the lower part of the spiral rod and confined between the pin 16 and the lower cross-piece 9. A handle 20 is secured to the top of thespiral rod.

In operation pressure downward on the handle causes the respective loops to run on the right and left portions of the spirals, respectively, and so said loops are rotated in opposite directions. When the pressure is released, the spring lifts the handle and spiral and produces the reverse motion of both loops. Hence there is an opposite motion of both loops both on the downstroke and on the reverse. This gives a compound action which is very effective and rapid for the purpose intended.

I claim 1. In a-beater of the kind stated, the combination of outer and inner rotary loops, and a rod having right and left spirals working respectively through openings in the respective loops, shaped to engage the spirals to produce rotation of the loops by reciprocation of the rod.

2. In a heater of the kind stated, the combination of inner and outer rotary loops having a common axis, the outer loop having an upwardly-projecting extension, and a rod having upper and lower right and left spirals movable respectively through openings in the extension and the inner loop, said openings being shaped to engage the spirals and produce rotation of the loops by reciprocation of the rod.

3. In a beater of the kind stated, the combination of an outer rotary loop having upwardly-projecting side pieces and upper and lower cross-pieces connecting the same, an inner rotary loop having the same axis as the outer loop, a rod having an upper spiral in one direction extending throu h an opening in the upper cross-piece and a ower spiral in the opposite direction extending through an opening in the lower loop, said openings being shaped to engage the spirals and rotate the loops, and a spring coiled around the rod between said upper and lower cross-pieces.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ANDREW J. THOMPSON.
